Kicker Impulse 15i, an exceptional subwoofer from Stillwater Designs, delivers earth-shaking bass for an immersive audio experience. Its stitched surround prevents cone/surround separation, while the extended pole piece reduces non-linear magnetic fields for improved heat sinking. The vented pole piece alleviates pressure under the dust cap for enhanced low bass, and the high-temperature Kapton voice coil former eliminates cone meltdown. With its powerful tinsel lead wires and rigid copolymer cone, the Impulse 15i ensures superior performance and durability.
